why energy drinks are bad for you?
Safety. Large amounts of caffeine may cause serious heart and blood vessel problems such as heart rhythm disturbances and increases in heart rate and blood pressure. Caffeine also may harm children's still-developing cardiovascular and nervous systems.
Though sometimes confused with sports beverages, energy drinks are a different product entirely. They are marketed to increase alertness and energy levels, containing significant amounts of caffeine and as much or more sugar as in soda. Many energy drinks pack about 200 mg of caffeine, the amount in two cups of brewed coffee. Other substances purported to increase energy may be added, like B vitamins and herbs such as ginseng and guarana. Most concerning is a lack of regulation about the safety of these drinks, as well as aggressive marketing tactics geared toward adolescents. The Centers for Disease Control and Prevention reported that in 2007, 1,145 adolescents ages 12 to 17 went to the emergency room for an energy drink-related emergency. In 2011 that number climbed to 1,499.
After water, sugar is the main ingredient in energy drinks. A nutritional comparison shows that a 12-ounce cola drink contains about 39 grams of sugar, 41 grams of sugar in an energy drink. Research has found that consuming high-sugar drinks of any kind can lead to weight gain and an increased risk of type 2 diabetes, cardiovascular disease, and gout.
Because of the amount of sugar and stimulant ingredients, there is concern that these beverages may not be helpful, and even worse, harmful to adolescents and people with certain health conditions.
Sipping a beverage that offers quick energy may appeal to people who feel fatigued or who believe the caffeine can provide an edge when exercising or playing competitive sports. Although statements on the websites of energy drinks warn that these beverages may not be suitable for children, youth are among their largest consumers. An energy drink may be used by adolescents or college students cramming for exams through the night, or by a young athlete before an important game. While it is true that some controlled trials have shown temporary improved alertness and reversal of fatigue after taking energy drinks, as well as enhanced physical performance in young athletes, the majority of studies show an association with negative health effects. These include increased stress, aggressive behaviors like fighting, alcohol/cigarette abuse, increased blood pressure, increased risk of obesity and type 2 diabetes, poor sleep quality, and stomach irritation.
A typical energy drink may contain the following: carbonated water, around 40 grams of sugar (from sucrose and/or glucose), 160 mg or more of caffeine, artificial sweetener, and herbs/substances associated with mental alertness and performance but that lack scientific evidence with controlled trials (taurine, panax ginseng root extract, L-carnitine, L-tartarate, guarana seed extract, B vitamins).
Water that is calorie-free and accessible without cost to most people is the beverage of choice taken with and between meals. Energy drinks are a source of caffeine that people may choose as an alternative to coffee or tea. However, they also contain high amounts of sugar, vitamins, and herbs that may not be necessary for the average person. Energy drinks can pose a health risk in vulnerable groups including children, teenagers, pregnant women, and those with medical conditions like diabetes and cardiovascular disease. Adults who choose to consume energy drinks should check the label for caffeine content and avoid high consumption (over 200 mg of caffeine per drink); consumption in combination with alcohol should be avoided. Pediatricians should discuss the use of energy drinks with their young patients and parents to ensure that all are aware of the health risks, and if used, are monitored carefully.
